[Abstract]:The Hafaya oilfield is located in the southeast of Iraq, and there are many oil-bearing strata in the production. There are many production problems such as high gas-oil ratio, sulfur content, sand production, asphalt precipitation and so on, which brings great challenge to the choice of artificial lifting mode. In order to select the suitable artificial lifting mode according to the characteristics of different strata, considering the reservoir characteristics, fluid properties, wellbore conditions, lifting equipment characteristics and the cost of funds, and so on, many factors, such as reservoir characteristics, fluid physical properties, wellbore conditions, etc. A comprehensive evaluation model of the factors affecting the artificial lifting mode of the target strata in Hafaya Oilfield is established by using the multistage fuzzy evaluation method. The decision factors of various lifting modes are calculated in combination with the present production situation of the oilfield. The best way of manual lifting is selected by stratified system. The pilot test of oil field shows that the practical application effect of the optimal selection result is good in technology adaptability and reasonable cost control in economy. It provides technical guidance and experience for the later stage of comprehensive conversion to artificial lift production in oilfield.
